TO ALL WHOM ITMMAYl CONCERN:

Be it known `that PATRICK WELCH, of the city, county, and State of NewYork, have invented certain improvements in Machines for Dressing and-Finishing Printers Types; and I do hereby declare that the following isa full, clear, and exact description thereof, reference being had to theaccompanying drawing, and to the letters of reference marked thereon.

The object of my invention is to dress and finish printers' types afterthey comefrom the moulds in a rapid, cheap, and efficient manner. This Iaccomplish by setting the types up in a manner hereinafter set forth,and by means of a bed or table provided with'a groove or channel, whichis'formed by bolting or otherwise securing to said bed suitable guides;throughthis channel, the types standing upon their feet, are fedbxpuitable feeding devices, and their sides and edges are properlyrubbed and Adressed. by knives or cutters set in the sides of saidchannel. Upon or connected with this table are suitable frames or slidesfor holding and moving the types while in form.

" In the accompanying drawings- Figure 1 is a plan of my machine.

Figure 11 is a detail view of a portion of the feed-bar and pusher forfeeding the rows of types into the machine. b

A is the bed of the machine. On this bed there is a table or raisedportion, on which the types are placed in form, with rules between thelines, previous to their being operated upon. C is another `table orraised portion, on which the typesare set after passing through thechannel where they are dressed or finished. D is the feed-bar forforcing the types through the machine. t is operated by the lever E,which has its fulcrum at F, one end being connected to the feed-bar, D,by the sliding joint H, and the other havinga slot in it through whichthe rller or crank-pin, I, works to drive the said lever by means of4the wheel J. K is a stationary sup` poi-'t for the feed-bar, D, and italso serves as a portion of one side of the channel through which thetypes are fed. L L are beds for the knives M M and the extra knives N N,for trimming oii the projections around the faces of thctypcs, aresecured partly bysaid bed and partly to the knives, M M. lThe knives, MM, are set at any angle, so that they will cut downward along thesurface of the types, and as the types are set closely togetherthe'knives are thereby prevented from leaving any burr or feather onthecorners of the types.v The knives, M M5 are made adjustable by thescrews, O O, by which they are drawn outward, and by the screws, P P, bywhich they are s'et further in when desired. The screws, Q Q, fastenthem firmly when they are in the right position. The hui-ves, N N, swingon the screws, R R, and are adjusted and fastened by the screws S S. Tis a stationary guide for the types after' they have passed the knives.A movable guide, U, supports the other side of the row until it iilled,when the said movable guide is raised, and the pusher, V, pushes thetype over on the table, C. The channel through which the types are madeto pass is made up on one side by a rule which rests against thestationary piece, K, the knife-bed, M, and the stationary guide, 'l,\andon the other side by the rule between the first two lines of types, theknife-bed, M, and the movable guide, U. The bottom of this channel isformed by the top of the table, B, the adjustable support, W, and thetop of the table, C.' The knife beds, L, and the knives, M, extend downbelow the surface of the channel, and slots or openings, a a, are outinto the support,'W, to allow the knives to be set near enough toaccommodate the thinnest types, while, for the thickest there is alwaysan unbroken track or support under the centre of their feet; Thesupport, W, is -adjusted so that it shall always be in the middle of thechannel by means of a screw, Z5. Y is a slide on which the knife bed, L,is secured. It may be adjusted to lregulate the width of the channel bythe screws, e e, acting on the stationary post, d, and is secured lirmlywhen in the position by the screw, e. The types to be operated upon areset up in form with rules between the lines, and placed on the table, B,where they are securely held on one side by the Hange or guard, f, andon the other by the movable guard, g, which is pressed firmly againstthem by the. spring, 7L. 0n the side nearest the operator the types areheld upnby a piece of furniture, z', against which the frame or pusher,j, acts in feeding up the form. The frame, j, is moved at the propertime by the pawl, Z, and ratchet-wheel, le, which in turn are operatedby the cam, m, on the shaft, n, as seen clearly in iig. 4. o is aspring, which by pressing down on the bar, p, draws backA the pawl, Z,by means of the rod, q, when the cam, m, allows it to do so. On theshaft, r, on which the ratchet-wheel, k, is fixed, are two pinions, s s,which mesh into teeth on the under side of the frame, j, and thus moveit forward. The movable guard, g, is made to yield to allow the types tobe readily emptied or placed on the table, B. On the inner end-of thesaid guard is a spring-catch or stop, u, which holds theend of the leadwhich is next to the line of types operated upon from springing iu anddisarranging the form when the pusher, t, on the feed-bar, D, is movedforward. The manner in 'which the said spring-stop n operates to holdthe lead next to the row of types to be operated upon is clearly seen intig. 7, where the projection, 4, holds the lead, 5, from springingforward. This spring-stop is pushed back out of the way by the pusher,t, when it returns, as seen in hg. 1. This spring-stop, u, is adjustedto suit types of diiferent thicknesses by means of the screw, v, on theguard, g. The slide or rest, w, in which the cuter end of the guard, g,slides, is adjusted to suit the diiferent widths of the form by thescrew, y; a a are guides in which the frame, j, slides. Thepusher, t, isadjusted. by the screws, f f. This pusher is 4secured to the feed-bar,D, by the screw, 2, and can be vibrated or swung on. saidscrew as acentre. It is held in any desired position by the screws, ff, which workin lugs or projections, 3 3, on the said feed-bar, D. After a row oftypes has been pushed from between the leads, the lead which liesagainst the stationary piece, K, and which rests upon the stops, b b',is allowed to drop down out of the way by the removal ofthe said stopsfrom under it. The said stops, Za 6', are swung out so as to release thesaid lead by the inclined slide, c', on the wheel, J, which trikes thearm, d', on the rock-shaft e', and thus throws out the stops, b, andallows the lead to drop through the table. After the types have passedthe knives they are pushed on into the channel between the guides, T andU, untilthe said channel is full, when the movable guide, U', is raisedby means of the cam, g', acting on the lever, L, which has its fulcrumat z", and is attached at j to the post, c, which it raises, carrying npthe rod, Z, towhich Athe movable guide, U, is attached. So soon as thesaid guide, U, is up and out of the way the pusher, V, is pushed forwardpushing the row of types into the forni on the table, C. The pusher, V,is operated by the cam, m', acting upon the projection, a', on the rod,o', thereby operating the lever, p', which has its fulcrum at q', andwhich pushes the pusher, U, in at the proper time. 'r' is a cam whichacts on the lever, e', to operate a stop or holder, t',A pushing itforward against the type next to the last one in the line which is to bepushed over on the table, C, thus holding said type between the' saidholder, t, and the guide, u, and preventing it from falling down in theway or twisting around, as the last type in the line passes from beforeit. u is an adjustable guide `to hold thc types on the table, C, inform;it is made adjustable by the screws u 11 and the spring/w', so that ifit is found on operating the machine that a type passesso as to take inthe said type, or else set further in, so as to givebcaring enough tohold the said type firmly. The guide or guard, y', is also made capableof yielding, so that if an extra type should be set up in a line theAsaid guide, y', may not be bent or any other part of the machine broken.The guide, y', yields by means of the spring a2 a2, and is held firmlyin place by the bolts, b2 112, which pass through slots in the guide,y', and enter the table, C. c2 is the driving pulley, and d2 the drivingshaft. On the said shaft is a mitre gear, c2, Whichmeshcs into a similargear, e3, on the shaft, n, thereby driving the shaft, u, and a pinion,f2, which meshes into, the Wheel, J, and drives that. g2 are hangerswhich support the shaft, n. h2 is a spring which throws down thc lever,E, as the crank-pin, I, passes the centre. t? is a stop which is held upagainst the end of the line of types by the weight, jz, and thusprevents the. said line from falling into pi as it advances.

The types to be operated upon are set up in form in the followingmanner: All the projections on the` ascending letters, such as the d, k,and Z, and on the descending letters such as the q, p, and y, are set inone direction, the body of the types being always set lengthwise in theline and the faces upward, as seen in iig.

By this means the projection on the edge of each of the sort of typesmentioned sets over or upon the shoulder of the next typein front orrear of it, thus allowing the shanks of the types to set snuglytogether, thereby -obviating the liability of their becoming bent orbroken by pressure in pushing them through 'thel lmachine. Between theserows of types narrow leads should be placed, the said leads being sonarrow as not to come quite up to the projections around the faces ofthe types, thus preventing said projections from striking or :ribbingagainst the said leads or against the types in the adjacent lines. Thetypes should always be first set with the body of the types forming thelength of the line and the thickness of the types forming the thicknessof the lines; and after the sides of the types have been dressed in thisposition the form is again divided into lines by leads forming lines, inwhich the body of the types are cross-wise in the lines, and being againput through the machine in this position they are finished on theiredges. Types other than those of the ascending or descending kinds arel'irst set up with the body lengthwise of the line in a similar manner.The form is thenV placed on far beyond the guide, u', that the holder,t', will not hold it firmly, the said guide, u', may be set further out,so'

the table, B, the lines parallel to the pusher, K, and the furnituie,z', and frame, 7L-pushed up snugly against the types, and the pawl, Z,adjusted. Power being then applied to the driving shaft, the form is fedup, one line at a time,to be pushed through the channel by the pusher,t; while being pushed through, there is a lead rest- .ing against thestationary guide, K, then a row of types, to be operated upon by thepusher, t, and then another lead, which is prevented from fallingforward, when the types pass from in front of it by the spring stop, u.The pusher, t, pushes bthe line of types into and through the channelbetween the knife beds, L L. In passing through this channel theshoulder knives, N N, remove the projection which is formed on the typesat the junction of the matrix with the mould. i The first pair ofknives, M, cuts or trims off the most of the roughness on the surface ofthe types, after which the second pair completely smooths and\dressesthe sides of the types.

'After passing the knives, the types are pushed on into the channelbetween the guide T and the guide U, when they are set over, a line at atime, into the table, C. When the whole vform is dressed in this manner,the dressed types on-the table, C, are divided into lines by rules, thetypes in each line being equal in number and with the body of the typescrosswise of the line; the machine then beingadjusted to suit thedierence between the thickness and the body of the types, they are putthrough again and the edges finished. i

Having thus fully described my invention, I claim- 1. Setting up vthetypes in lines standing upon their feet, in the manner described, toprepare them to be fed to the machine, substantially as herein setforth.
